This chapter describes how you can use Oracle Event Processing Visualizer to deploy, suspend, update, and uninstall Oracle Event Processing applications.
This chapter includes the following sections:

Deploying an application refers to uploading to the server the JAR file that contains the application and then installing it, which makes it available to clients.
Oracle Event Processing internally deploys an application as a two step processes. The first step involves starting the application bundle inside the OSGi container. The second step involves starting and initializing the application. Because the second step is asynchronous in nature, Oracle Event Processing Visualizer does not wait for the completion of the second operation. As soon as the application has successfully started, the Oracle Event Processing Visualizer navigation tree is updated automatically with the new deployment and a successful message will be sent to the dashboard. However, if the application fails to start, you must check for errors on the server side because no messages/updates will occur on the Oracle Event Processing Visualizer.
When you deploy an application, the Oracle Event Processing server starts a new configuration history for it. See Configuration History Management.
You may only deploy to a group if the target Oracle Event Processing server is part of a multiserver domain (that is, if clustering is enabled). You may not deploy to a group if the target Oracle Event Processing server is part of a standalone-server domain (that is, if clustering is disabled).

This section describes how to deploy an application to a standalone-server domain. For information on deploying an application in a multiserver domain, see Deploy an Application in a Multiserver Domain.
Deploy an Application in a Standalone Server Domain
This section describes how to deploy an application to a multiserver domain. For information on deploying an application in a standalone-server domain, see Deploy an Application in a Standalone-Server Domain.
For more information, see Multiserver Domains.
Deploy an Application in a Multiserver Domain
You can temporarily suspend an application from running and resume the operation using the Suspend and Resume operations in the Deployment screen.
Suspend or Resume an Application
You can update your currently existing application with your latest application using the Update operation in the Deployment screen.
When you update an application, the Oracle Event Processing server erases the application's existing configuration history and starts a new configuration history for it. See Configuration History Management.
Update an Application
When you uninstall an application, you completely remove it from the server so that you can no longer access it.
When you uninstall an application, the Oracle Event Processing server erases the application's existing configuration history. See Configuration History Management.
Uninstall an Application
